A young MC Ride--yeah, the Death Grips MC Ride--is featured on this Mxlplx video for "Civic Duties." The video seems to be shot in the same scenic, highway-convenient location as this Swank Daddy video for "I'm A Man":

Ride clearly appears in the background of that video as well.

Considering how potent Ride's style is, it only make sense that he built up to it with a series of demos and probably long-forgotten projects. Something like the Money Store doesn't drop out of thin air, and this is proof.

Edit:

Found more videos. Oh, man! Here is Ride featured on other videos from musical co-hort Fyre:
